listening to a reeeally old Space Show with Elon Musk, and he has to field a question about the 'face' on Mars. painful but interesting.

A: Why have 4 contingency landing pads?

I posted this question on the unofficial SpaceX facebook page (https://www.facebook.com/groups/spacexgroup/) and here are a few answers: I do not think there is any evidence for these extra pads having been built yet. 2 side cores return there while the 3rd center core lands out to sea on a bar...

Alright... so this person posted this on a facebook page, waited for comments, and then copied them over to an answer.

and they want points for that...

As long as any valuable information turns up, that is probably OK. No upvote from me though

kim holder

nope, i don't count that as okay. that is unreferenced opinion, and there is no sign the answerer did any work themselves

Hohmannfan

...and upon reading through that answer, hardly any useful answer turns up at all.

Sir Cumference

Will the Sun use the proton-proton reaction when it becomes a red giant?

I'm making a star core simulator and I can't figure it out

Hohmannfan

18:13

@SirCumference I think I remember that the proton-proton reaction is still important in large stars, but there is others too

going to wiki...

Sir Cumference

Maybe the CNO cycle?

Hohmannfan

Sounds familiar. Yeah

Sir Cumference

All right, thanks a lot

duzzy

I thought the CNO was only for stars with more mass.

Hohmannfan

Too long ago I read anything about it, but is not the CNO rate increasing with age too?

duzzy

18:16

Possibly. I don't remember entirely. I just thought it was only with more massive stars.

The sun will do the proton-proton thingy, and then start turning helium into carbon

Hohmannfan

"This strong temperature dependence has consequences for the late stage of stellar evolution, the red giant stage." (about triple alpha on wikipedia)

Sir Cumference

But would it ever undergo the CNO cycle?

Hohmannfan

The Sun does a little CNO even now.

Sir Cumference

Well yeah

But it mainly does the pp reaction

Christ I'll have to read a lot...

Soyuz going to launch soon.

lol well that was pretty terrible timing for a video feed to cut out.

@duzzy heck, i was out and missed it.

NASASpaceFlight.com: Soyuz 2-1B suffers rare pad abort during Resurs-P attempt

posted on March 12, 2016 by Chris Bergin

A Russian Soyuz-2-1b rocket has aborted a launch attempt with the latest Resurs-P (No.3) remote sensing satellite for Roskosmos. The launch attempt took place from Site 31/6 at... No related posts.

@PearsonArtPhoto what does it mean when an answer is grayed out unless i hover over it?

@kimholder Not sure. Do you have an example?

I think that it's negative scored.

i don't recall running across it before

PearsonArtPhoto

Might be new, not sure.

I see that happen when it's something like -3 or worse.

Almost like SE is saying "Yeah, it exists... but nothing to see here. Move along."

@StackExchange Ah, so they aborted.

It was strange. The video feed went dead just seconds before it was supposed to launch.
